The Intel manual changed the name of the CPUID bit to match theinstruction name. We should follow suit for sanity's sake. (See Intel SDMVolume 2, Table 3-20 "Feature Information Returned in the ECX Register".)

[ hpa: we can only do this at this time because there are currently no CPUs with this feature on the market, hence this is pre-hardware enabling. However, Cc:'ing stable so that stable can present a consistent ABI. ]
